Each country has its own standard time primarily due to the Earth's rotation and the need for synchronization within its borders for social, economic, and political activities. As the Earth rotates, different regions experience daylight and nighttime at different times, necessitating local timekeeping. Additionally, standard time helps facilitate trade, communication, and travel within and between countries. Adopting a uniform time system ensures that schedules, such as business hours and transportation, align effectively.
The type of time kept by each community using the sun's zenith on its own meridian is called "solar time." Solar time is based on the position of the sun in the sky, specifically when it reaches its highest point, or zenith, at noon for that specific location. This system can vary from standard time due to differences in longitude and local practices.
Standard time was created to establish a consistent way to measure and track time across different regions, which was necessary for the coordination of transportation and communication networks, such as trains and telegraphs. Before standard time, each town or city would set its own local time based on the position of the sun, leading to confusion and inefficiency in scheduling activities.
local timeThe time of a place when the midday sun is overhead is called local time.It changes from place to place.The place on the same longitude has the same local time.standard time The local time of the standard meridian of a country is called standard time.It remains same for that particular country.the place on the same longitude has the different standard time.The main difference between local time and standard time is, the local time changes from a place to place, but the standard time remains fixed for the particular country. As per local time, the place/location on the same longitude will have the same local time, but as per the standard time the place on the same longitude will have different standard time.
coz it was okay !!!! Standard time zones in the United States are currently defined at the federal level by law 15 U.S.C. §260. The federal law also establishes the transition dates and times at which daylight saving time occurs, if observed. It is ultimately the authority of the Secretary of Transportation, in coordination with the states, to determine which regions will observe which of the standard time zones and if they will observe daylight saving time. As of August 9, 2007, the standard time zones are defined in terms of hourly offsets from UTC.[1] Prior to this they were based upon the mean solar time at several meridians 15° apart west of Greenwich (GMT). Only the full time zone names listed below are official; abbreviations are by common use conventions. The United States uses nine standard time zones. From east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC−11) and Chamorro Standard Time (UTC+10).

Before the advent of the railroad, most Americans kept time based on local solar time, with each town setting its own clocks according to the position of the sun. This led to a patchwork of timekeeping across the country, causing confusion, especially when scheduling transportation. The expansion of railroads necessitated a standardized time system to coordinate train schedules efficiently, as trains traveling long distances would encounter different local times. Consequently, in 1883, the U.S. adopted a system of standard time zones to streamline operations and improve safety in rail travel.
Each country sets its own time zone(s) and Daylight Saving Time/ Summer Time schedule, if any.

In 2004, the standard VAT (Value Added Tax) rate varied by country. For example, in the UK, the standard VAT rate was 17.5%. In the European Union, VAT rates ranged from around 15% to 25%, depending on the member state. Each country set its own rates, so it's essential to specify which country you are referring to for a precise answer.
